It might be another 3-4 months before I decide on a thumbnail species and buy them, but until then I'm just researching each species so I can figure out which one to buy first.

I just thought of this question; it has to do with providing a water dish.

My Leucs and Azureus are always hanging out in their water dishes. Sometimes alone and other times there may be two or three of them. I use the shallow green ceramic type.

Do any of you provide a water dish for your thumbnails? Is it necessary? I ask this because I don't usually see a water dish in most thumbnail set-ups.
